DEC6108 Video Wall Code Adaptation Rule

Publication Date:  2019-04-25 Views:  22 Downloads:  0
Issue Description
When the Decoder DEC6108 (V1R2C30SPC200) is added to the IVS client, if Code stream selection is set to Do not specify a stream in the channel parameters, or Code stream selection is not available on the IVS client corresponding to the earlier C50 commercial platform, the decoder adaptively selects a code stream of a proper resolution according to the screen splitting. For engineers who are not familiar with the decoder adaption rules, the adaptive results may be messy. Therefore, a detailed adaption rule matrix and a real-time resolution checking method are provided.
Solution

To view the resolution when a video is played on the video wall, perform the following steps:

1. Log in to the decoder using SSH. The default user name is admin and password is Change_Me.

 2. Run su - root to switch to user root. The default password is Change_Me.

3. Run cat /proc/umap/vdec to obtain the real-time resolution of the IPC.
